.Dt SSL_GET_CIPHERS 3
.Os
.Sh NAME
.Nm SSL_get_ciphers ,
.Nm SSL_get_cipher_list
.Nd get list of available SSL_CIPHERs
.Sh SYNOPSIS
.In openssl/ssl.h
.Ft STACK_OF(SSL_CIPHER) *
.Fn SSL_get_ciphers "const SSL *ssl"
.Ft const char *
.Fn SSL_get_cipher_list "const SSL *ssl" "int priority"
.Sh DESCRIPTION
.Fn SSL_get_ciphers
returns the stack of available
.Vt SSL_CIPHER Ns s
for
.Fa ssl ,
sorted by preference.
If
.Fa ssl
is
.Dv NULL
or no ciphers are available,
.Dv NULL
is returned.
.Pp
.Fn SSL_get_ciphers
returns a pointer to an internal cipher stack, which will be freed
later on when the
.Vt SSL
object is freed.
Therefore, the calling code must not free the return value itself.
.Pp
The details of the ciphers obtained by
.Fn SSL_get_ciphers
can be obtained using the
.Xr SSL_CIPHER_get_name 3
family of functions.
.Pp
.Fn SSL_get_cipher_list
returns a pointer to the name of the
.Vt SSL_CIPHER
listed for
.Fa ssl
with
.Fa priority .
If
.Fa ssl
is
.Dv NULL ,
no ciphers are available, or there are fewer ciphers than
.Fa priority
available,
.Dv NULL
is returned.
.Pp
Call
.Fn SSL_get_cipher_list
with
.Fa priority
starting from 0 to obtain the sorted list of available ciphers, until
.Dv NULL
is returned.
